y=4x
put this value of y in 3x-y=1
3x-4x=1
-x=1
x= -1
y=4(-1)
y= -4
So (x,y) ordered pair is (-1,-4)
Answer:
3x-7y
Step-by-step explanation:
9x^2 - 49y^2
find the square root of a values

The midpoint M of two endpoints of a line segment can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(12,9), B(-2,-5)
The midpoint M is

We have the final answer as
<h3>M = ( 5 , 2)</h3>
